I LOVE this strategy that my tutor taught me in year 12!
He said:
Whenever you lose the motivation to study (maybe it's been a few hours, or maybe you're just not feeling it), take a 10-minute walk outside, come back to your desk, log onto the NESA website and print a past paper, throw out everything except for the multi-choice questions, set a 15-minute timer and do as many as you can!
This is a super simple, quick way to study across your subject without having to sit there for hours or read through a tonne of notes!
After the 15 mins are up, go back and mark it to see how you did!
Give it a like if this is something you've tried 🙂
